FUEL EFFICIENCY (Rolling Resistance)

There is a 7.5% loss of fuel economy between the best and worst class (average).

WET GRIP (Braking Performance)

Wet grip is one of the most important performance characteristics in a tyre.

The effect may vary among vehicles and driving conditions, but in the case of full braking, the difference between a G and an A class for a set of four identical tyres could be up to 30% shorter braking distance (e.g. for a typical passenger car driving at 80 km/h speed this could be up to 18m shorter braking distance).
